Strange issues as well as "Ghost" data points when plotting #892

Closed tomhajjar closed 2 months ago

tomhajjar commented 2 months ago

The past week I noticed a number of old projects didn't work the same anymore and there are "ghost" data points being plotted in areas they shouldn't be in. Files updated 8/19/24

Update:

I retraced my steps and redid a number of sub-circuits in the project (cosmetic changes) and cannot get the "bad data" issue to reoccur. "Ghost" data points are still present as shown in attached screen shots

The goal of the project is to make more RF "TLine" components that work under ngspice. So far TLines, Lossless Directional Coupler and a 90 deg Hybrid coupler working.

I confirm this problem. The virtual point at (0,0) is always rendered. All point-type plots are affected. I will provide a fix soon. The most probably I will prepare v24.3.1 release in September containing this fix, because the reported bug is critical.
